Projection apparatus, decoder, and image processing method for the projection apparatus

Abstract

A projection apparatus, decoder, and an image processing method for the projection apparatus are provided therein. The projection apparatus includes a projection module, a decoder, and an optical device. The projection module is used for alternately projecting first projected images and second projected images according to a three-dimensional video signal. The decoder is coupled to the projection module, and used for receiving and decoding the three-dimensional video signal to generate and wirelessly transmit a status signal. The optical device is used for receiving a frame switching control signal outputted from the projection module, used for receiving the status signal from the decoder, and use for receiving the first projected images and the second projected images in an image receiving status.
